Dang it!! I hate when I hit send in error.  Let me state the top part of
that message again.

There are several disconnects here that I think need to be straightened out
all at once.


   - model.getSeq/Alt/Bag( resource ) - if the resource doesn't exist the
   result is in the model of the resource.
   - model.getSeq/Alt/Bag( resource ) - if the resource exists in the model
   the result is in the model of the method.
   - model.getSeq/Atl/Bag( text ) - always returns a result in the model of
   the method.
   - The documentation states that changes to the result may change the
   model implying that the result is in the model of the method.
   - model.getResource( text ) - always returns a resource in the model of
   the method.
   - model.getResource( text ) - states that the method behaves identically
   to model.createResource( text )
   - model.createSeq/Alt/Bag( resource ) - always returns a result in the
   model of the method.
   - model.createSeq/Alt/Bag( text ) - always returns a result in the model
   of the method.
